EL DORADO. County seat, Placerville. Created February 18, 1850. El Dorado — the far-famed fabulous region of genial clime and never-fading verdure, where gold and precious stones are as common as rocks and pebbles, where wines gently flow from fountains. The name, meaning “the gilded one” in Spanish, appears at the beginning of the 16th century as that of a mythical Indian chief who was said to have been covered with gold dust during the performance of religious rites. When the discovery of gold by James W. Marshall at Coloma in January 1848 became known to the world, California, and particularly that section where gold was discovered, was called “El Dorado.” From this fact the county received its name.
